I saw a great white throne, and Him that sat on it, from whose face the earth and the heaven fled away. And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books.@Revelation 20:11-12

Haldor Lillenas (1885-1959)

Have you found redemption thro’ the Son of God?
Are you ready for the judgment day?
Are you sheltered underneath the precious blood?
Are you ready for the judgment day?

Refrain

Are you ready for the judgment day?
Are you ready for the judgment day?
When you stand before the throne,
Will His blood for you atone?
Are you ready for the judgment day?

You have long refused your blessèd Lord to own;
Are you ready for the judgment day?
What will be your fate before the great white throne?
Are you ready for the judgment day?

Refrain

How shall you escape the burden of your guilt?
Are you ready for the judgment day?
If you scorn the blood that for your sin was spilt,
Are you ready for the judgment day?

Refrain

Will you trust the Savior to forgive your sin?
Are you ready for the judgment day?
He can save, no matter what your life has been;
Are you ready for the judgment day?

Refrain
